Manifold

[Terry McGrath]

I had a manifold recently which would not separate from the block. There was no way of telling what held it. I eventually resorted to brute force & higgerence. The centre stud had seized in the iron casting and it took a chunk of the block with it to the depth of the thread.
Fortunately it had not broken into the ports or the water jacket. I superglued the bit back in and plugged the tapped hole. It's since done many thousands of miles on my RF saloon.
